WRIST-PIN" ASSEMBLY FOR METER VALVES.

Application filed February 19, 1927. rSerial No. 169,661.

The present invention relates to an improvement in valve cover and valve wrist pin assembly for meters generally and more particularly designed for gas meters as at present universally used.

Heretofore the valve cover and valve Wrist pin have been united by solder. This construction while satisfactory at first, becomes, through constant usage, loosened allowing the wrist pin to drop away from the valve cover, thus interrupting the funct-ioning of the valve. To overcome this structural weakness, the uniting of the pin with the valve cover is the principal object of the present invention.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and set forth in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To comprehend the invention, reference is directed to the accompanying drawings, wherein Figure l is a perspective view of the valves of a meter and their operating mechanism.

Figure 2 is a plan view of one of the valves with the valve cover arm connected with the valve wrist pin.

Figure 3 is a sectional view taken on line 3-3 of Figure 2.

Figure 4 is a sectional view illustrating the wrist pin mounting shank embedded in the valve cover.

Figure 5 is a sectional view on line 5-5 of Figure 2 illustrating the preferred mounting of the wrist pin within the eye of the shank.

Figure 6 is a perspective view of the valve wrist pin illustrating the reduced lower end.

Figure 7 is a perspective view of the shank.

Figure 8 is a perspective view of a portion of the valve arm cover which connects with the valve pin when in assembled relation.

In the drawings wherein like characters of reference designate corresponding parts the numeral 1 indicates the upper compartment of a conventional type meter boX. The numerals 2 represent valve seat-s upon each of which is mounted for horizontal movement a valve seat cover 3, each cover being provided with the conventional valve cover guide wires 4 passing through and reciprocating in wire guides 5, the wires 4 and the guides 5 holding the valve cover in position to reciprocate upon the valve seat. EX- tending from each valve cover is a shank 6 wedge shaped in plan, the base of said shank being embedded in its associated cover by being cast therein. The shanks so mounted become an integral part with their associated covers as shown in Figure 4 of the drawings and are thus prevented from becoming loosened due to the constant use of the valve. The free end of each shank 6 is provided with an aperture or eye 7. 9 is a cylindrical valve wrist pin having a reduced lower end portion 10 cored as at 10 and one is adapted for insertion within each eye 7 so that the edge of said cored portion may be swaged over the peripheral edge of the eye 7, thus retaining the valve wrist pin within said eye with the shoulder 8 resting on the upper surface of the shank 6 surrounding the eye. The casting of the respective shanks 6 in their associated valve covers insures a rigid and permanent attachment which is not liable to work loose. The formation of the valve wrist pins with a shoulder 8 and the swaging of the lower core and end of each to force its periphery into contact with the under surface of the material surrounding the eye, insures a rigid permanent connection between the pins and their respective Shanks, one which will not work loose during the Operation of the valve cover and one which is simple in assembly and may be cheaply manufactured. A valve cover operating arm 11 provided with an aperture 12, having a bushing 13 therein is adapted to receive each pin 9, said arms being pinned on the pins as at 14. The opposite ends of said arms are likewise apertured at l5, and are connected with a crank shaft 16 which shaft when rotated operates the valve seat covers 3 horizontally over their valve seats 2.

I claim z- A valve seat cover and valve wrist pin assembly for meters comprising a shank east in said cover and having a portion projeoting from one edge of the Cover, the projecting portion of said shank provided with an eye extending therethrough7 a cylindrical valve Wrist pin having aeored end of reduced diameter, the end of reduced diameter affording a shoulder at the base of the Wrist pin, said end being reeeived'Wit-hin said eye With the shoulder resting on said shank surface, said cored end being sWaged 10 GEORGE D.
